An interior angle is an angle in the inside of two lines, and the two lines have a line through them. Look at the line through them. The opposite angles on each side of the line are equal. That should be enough info to solve your problem
Use a protractor
Each interior angle measures 162 degrees.

Subtract the interior angle from 180
The measure of the exterior angle.
It is: 180-exterior angle = interior angle
They are all 60 degrees.

AnswerIt is Dodecagon.To find this, you have to first find the exterior angle of the polygon. Since the exterior angle of a polygon is always supplementary to the interior angle, you subtract the measure of the interior angle from 180. 180-150=30. Now You divide 360 by the measure of the exterior angle to get the number of sides of the polygon. 360/30=12. A 12-sided polygon is called a dodecagon
360/number of sides and deduct the quotient from 180 which will give the measure of each interior angle
Each interior angle will measure 156 degrees
